RUSSELL G. DUDLEY, OF NE\VARK, NEIV JERSEY.

COMBINED STEP-LADDER AND CHAIR.

SPECIFICATION forming part of Letters Patent No. 371,128, dated Q-ctober4 1887.

Application filed November 4,1856. Serial No. 218,003. (No model.)

T0 at whom it may concern:

Be it known that I, RUssELL G. DUDLEY, a citizen of the United States,and a resident of Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in CombinedChair and Step-Ladder; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a perspective View of my invention in theform of a chair. Fig. 2 is a vertical longitudinal section of the samein one form of a step-ladder. Fig. 3 isa vertical longitudinal sectionof another form of the step-ladder. Fig. 4 is a detail section.

My invention relates to a combined chair and step-ladder; and itconsists in the construction and novel combination of parts, ashereinafter described and claimed.

Referring by letter to the accompanying drawings, A and B designate therear legs of the chair, said legs being continued up ward to form theback rails of the chair. The back rails of the chair form the rear legsof the stepladder.

G designates the rigid portion of the chairseat, which is strengthenedby metal straps D, which connect the rear legs, A B, and the front legs,E F, to the seat proper. An extension, G, is hinged to the front edge ofthe seat 0, and when opened forms a portion of the seat 0. The hingedextension G is provided with a round, H, which, when the device is inthe chair form, is parallel with and contiguous to the round N betweenthe front legs of the chair. The extension G is provided with legs K L,which are connected by a transverse bar, H, which forms a step of itselfat one time-- z'. e., when the device is used as a step-ladder-and formsa round or crossbrace, in conjunction with a brace, N, between the frontlegs of the seat portion proper when the device is adjusted to the chairform. The legs K L are provided near their lower ends with pivoted'metalloops or links I which, when folded up out of the way, enter notches Qin the front edges of the legs K L. In the chair form these loopsembrace the chair-legs E F and serve to hold them in place.

The back-rest 0, between the upper ends of the back rails, is faced onits ends with metal strips to sustain wear, and is pivoted near what Iterm its normal upper edge between metal plates R on the inner faces ofthe back rails. The upper ends of metal straps S S are pivoted to theend edges of the back-rest O and pass through wire guideloops T, driveninto the inner faces of the back rails. These straps S S are provided attheir lower ends with flanges or stops, which prevent the withdrawal ofthe straps S S from the guide-loops T. Notches U are made in the strapsS S near their lower ends to engage the guide-loops T, to hold theback-rest O in a horizontal position to form the top step when thedevice is adjusted to form a step-ladder. The legs of the extension areprovided near their outer ends with stoplugs X X, which form rests andstops for the top step of the stepladder when the device has beenadjusted to that form. The metal loops P embrace the upper ends of theback rails of the chair when the device is changed to the step-ladderform.

Below the back-rest O, I provide an auxiliary back-section, Z, which ispivoted at the ends of So its upper edge between the back rails of thechair, said back rails being metal-faced at the pivoted points. Thisback-section Z is also metal-faced along its ends to sustain wear. Metalstraps a a are secured to the ends'of the auxiliary back-section Z, nearthe front edge of the same, and extend down through recesses b b in thechair-scat and through guide-loops or staples c c, driven into the innerfaces of the back rails below the chair-seat. The lower ends of themetal straps a a are provided with flanges or stops, which prevent themetal straps from being withdrawn from the staples c c. The metal strapsa a are provided with notches d d, which engage the staples c 0 when theback-section Z is raised to form a step.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The con1bination,with the chair-back, the back-rest hinged thereto,devices for supporting the same horizontally, and the seat fixed to theback and front legs, of the extension hinged to the seat and providedwith stop-lugs, and the metal loops pivoted to the outer ends of thesaid extension, substantially as specified.

2. The combination, with the back rails provided with the seat and themetal face-plates, of the pivoted back-rest provided with the pivotednotched metal plates S, the loops in the back rails, the seat and rigidlegs, and the extension hinged to the forward edge of the seat andprovided with the pivoted metal loops at its outer ends, substantiallyas specified.

3. The combination, with a chair having a back step pivoted between theupper end of the back rails and pivoted supporting-straps for the saidstep, of a back step pivoted between the back rails below the upper stepand provided with pivoted and notched metal straps at its ends, and thestaples in the chair-back for supporting the pivoted metal straps,substantially as specified.

step H, notches Q, stops X X, and loops P,

substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.
